HERMAN KAPOLKIN, or NEW YORK, N. Y.

CONCRETE RAILROAD-TIE.

To all whom it may concern 7 Be it'known that I, HERMAN KAPOLKIN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of. New York,have invented new and useful Improvements in Concrete Railroad-Ties, of which the following is a full, clear, andexact description. f p

Among the principal objects which the present invention has in view are: To increase the permanency of railroad constructions; to decrease the need of repair of rail road beds; to strengthen the=road bed construction; to facilitate the upkeep of the bed; to prevent the loosening of the rails; and to assist in retaininga train on the road bed in theevent of derailment.

Drawings.

Figure 1 is a cross section takenas-on the line 1-1 in Fig. 2, of a railroadtieof usual construction, showing in conjunction therewith, a fragment of a concrete tie, and metal reinforce therefor.

Fig. 2 is a plan view showing axfragmentrof the rail and the metal reinforce used in forming the railroad tie, the concrete with which the said tie is associated, being removed. r i

Fig. 3 is a plan view onreduced scale showing a fragment of a railroad rail and of completed concrete tie therefor, together with means for mounting said rail on said tie, a portion of the concrete being broken away to show the arrangement of the reinforce employed therewith. 1

Fig. 4 is a cross section, the section'being taken as on the line 44'in Fig. 3, the conconcrete structure being indicated by the broken lines.

Fig. 5 is a detailed view on enlarged scale showing the method employed for preventing the loosening of nuts on bolts 'used in the construction of the road bed.

Fig. 6 is a detailed view in perspective showing a foot for holding the rail in position.

Fig. 7 is an end view of a tie constructed in accordance with the present invention and showing in conjunction therewith, a fragment of railroad rail.

Description.

is cast and allowed to set around longitudiv nalmetal reinforce tie rods 13. The rods 13 as seen best in Figs. 2 and 3 of the drawings are disposed in parallel relation and are held from spreading apart by U-couples 14. Preferably the ties 13 and the couples 14 are constructed from tubing. The tubing from which the couples 14 are constructed particularly facilitates'the threading of the up-turned ends thereof to form the tapped sockets 15 which extend vertically to receive the bolts 16.

The bolts 16 as seen in Fig. 1 of the drawings are threaded and have each a head 17 which bears upon a foot plate 18 in service. The body 12 "is cast to provide a series of cross ribs 19 which are disposed between the rails 20 in service and are intended to form guide grooves to hold the Wheels of an engine or car on the road bed if the engine or car jumps the rails 20.

At the opposite ends'and between the upturned sections of the couples 14 are provided sockets or seats for heavy wooden bolsters 21. The bolsters 21 are surmounted by metal plates 22 on which the rails 20 rest. The plates 22 protect the bolsters 21 from the wear incident to the vibration of the rails 20.

The plates 22 are held in place by the bolts 16, perforations being provided in the said plates through which are extended the bolts 16. In service the plates 22 are spaced from the ends of the couples 14 as shown best in Fig. 1 of the drawings. By this means the vibration imparted by a passing train to the plates 22 is prevented from being transmitted to the body 12 of the railroad tie} The vibration or shock of the passing train is absorbed by the bolsters 21.

When building' a road bed wherein ties constructed and arranged as in accordance with the present invention are being used, theties are placed in a manner similar to that at present employed. The bolsters 21 and plates 22 are then placed in position to receive the rails 20.

When the rails 20 have been laid, the foot plates 18 are adjusted on the bolts 16 and these latter are introduced through the perforations provided in the plates 22 and are screwed into the tapped sockets formed in the upturned ends of the couples 14. Before tightening the foot plates 18 on the flanges of the rails 20, the ties are accurately disposed as is done in railroad construction. The ties having been placed, the bolts 16 are tightened with the result that the foot plates 18 are pressed firmly upon the flanges of the rails, forcing the same rigidly upon the plates 22. I

To look the bolts 16 in position, the keys 23.are driven home'in the grooves 24 provided in the foot plates 18. The keys223 are preferably constructed of wrought metal and are provided with upturned ends 25 which are driven against one side of the bolt head 17 asseen best in Fig. -of the drawings. The keys pass under the bolt heads 17, which it will be understood are not otherwise prepared for the said keys. The free ends of the keys 23 arethen upset to prevent their becoming loosein the grooves 24, with the possibility that they may escape :therefrom.

i It is obvious that while the keys 23 form an efficient lock? for the bolts 16, they may readily be'removed from service so that the bolts may Joe-tightened or "loosened as the exigencies of the case demand. The operation of loosening consists, first in striking down the free ends of the keys 23 and then driving them backward through the grooves 24 until the heads 25 free the heads '17. 1

- It. willvbe seenbest in Fig. lofthe drawings that the body of-the plates is'wso constructed that when the overhang '26 thereof bears firmly on the flangeof the rail 20, the said body-isslightly" removed from the-plates 22. Thus allowing fortightening of the plates 18 on the flanges of the rail.'

;After the rails haveibreen set, ballast of broken stone or other materials is placed'on the bed andtamped under and -'besidel the ties 12; To facilitate this operationthe body 12 0f the ties is providedv'with inclined surfaces-27 converging to a dependent ridge as shown bestinFig-7 of the drawings. The wedge-shaped space naturally formed under eachtie by reason-of this construction forms apocket for the loose stones orparticles of the ballast and faei litates-thetamping-which is provided to drivetherhallas'tbelow the said tife. Also during-the service I life of the tiesit becomes necessary: from time to time to steady the ties. The. tamping incident thereto is readily and-quickly performed by 5 reason of the formation of the bottom of the said ties.
